Traditional ammunition systems have not changed their principal materials of manufacture since the late 19th century. However, the construction of advanced, next-generation ammunition systems has evolved in recent years utilizing new materials including steel alloys, stainless steel, tungsten and even polymers. This change has expanded the performance envelop, significantly improving both ballistics and terminal performance while reducing cartridge weight. New materials require component surfaces to be properly engineered, specifically at the areas of engagement. This is especially important when the materials in the design are further apart in the electromotive series, and therefore more likely to react and corrode with one another. An example of this design consideration is in the use of exposed steel penetrators formed within a copper projectile. Coatings such as zinc have been used to delay corrosion of the steel penetrator. However, these sacrificial coatings have severe limitations that result in premature formation of white corrosion products even in moderate service conditions.<\/p>\n
\nPerformance Advantages of Dura-Nickel<\/h2>\n
The performance advantages of Dura-Nickel can be leveraged within a range of ammunition applications including hybrid or steel case designs and improved corrosion resistance over traditional nickels on standard brass or gilding metal.<\/p>\n
Dura-Nickel HP+\u00ae<\/strong> is a more cost-effective coating that can be used in most applications where radii of the components can be maintained at 0.020\u201d or greater.
\nDura-Nickel A1\u2122<\/strong> is a next-generation coating within the Dura-Nickel family that provides improved corrosion resistance, especially in applications where sharp tips and radii of components are less than 0.020\u201d.<\/p>\n![\"Performance](\"https:\/\/advancedplatingtech.com\/wp-content\/uploads\/2023\/02\/performance-duranickel.png\")

Sacrificial vs. Barrier Corrosion Protection \u2013 What is the Difference?<\/h2>\n
Corrosion resistance coatings fall into two primary categories \u2013 sacrificial or barrier coatings. The difference between the two lies in if the coating is more or less likely to corrode than the base

<\/a>material the coating is deposited on. Sacrificial coatings are more reactive than the base material, whereas barrier coatings are less reactive than the substrate. The advantage of sacrificial coatings is that thin coatings can provide moderate corrosion protection. However, sacrificial coatings will corrode in preference to the base material, producing corrosive products such as white rust as a precursor to base material corrosion. Barrier coatings must be deposited thicker to create a pore-free barrier between the atmosphere and the base material. However, a pore-free barrier coating will not produce sacrificial corrosion products.<\/p>\n
